From 71b91b4e4049aec2032d588093de523662bbaba3 Mon Sep 17 00:00:00 2001 From: Ajit Kumar Agarwal Date: Mon, 30 Nov 2015 14:21:07 +0530 Subject: [PATCH] [Patch,SLP]: Correction in the comment for SLP vectorization profitable case. Correction in the comment for vectoriable profitable case. The comment is contradicting the condition vec_outside_cost + vec_inside_cost > scalar_cost. ChangeLog: 2015-11-30 Ajit Agarwal * tree-vect-slp.c (vect_bb_vectorization_profitable_p): Correction in the comment.
